Title: Improvements in or relating to mass spectrometers
Inventor: DALY NORMAN RICHARD
IPC: H01J49/28
Filed: 1968-08-16
Abstract: 1,263,705. Mass spectrometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 21 July, 1969 [16 Aug., 1968], No. 39349/68. Heading H1D. [Also in Division G1] A mass spectrometer has an ion source comprising a non-forming portion, an intermediate electrode or electrodes and a final electrode, together with means for varying the potential of the final electrode relative to the intermediate electrode(s) and to the ion forming portion while causing substantially no variation in the potentials between the intermediate electrode(s) and the ion-forming portion, thereby reducing spurious variations in the abundance of ions extracted from the ion-forming portion as the potential on the final electrode is varied. As shown, ions are formed in chamber 1 from gas by collision with electron beam 2, and intermediate electrodes 3, 4, 5 produce a focused beam of ions 6 at the final electrode 8, which is normally earthed. A voltage source 7 is used to derive the appropriate potentials of chamber 1, electrodes 3, 4, 5 and ion repeller electrode 11 and a further voltage source 9 is connected through potentiometer 10 between electrode 8 and chamber 1. The mass spectrum of, for example, an organic molecule formed from its electron-impact induced disintegration may be examined by varying the potential V 2  between chamber 1 and electrode 8 to effect a scan of the mass spectrum across a slit in earthed electrode 12. Behind this slit is a detector comprising a glass disc 13 with an aluminium surface coating inclined to the ion beam which strikes the surface at about 80 degrees. This arrangement mounted in a metal cylinder 14 held at a high potential V 3  (typically - 30 Kv.), has a very high secondary electron coefficient, and the electrons are accelerated across to a facing plastic scintillator 16 having a surface of aluminium and which is coupled to a photomultiplier 17. The mass spectrometer may be of the single or double focusing type, and the ion source arrangement may, by reversing the potentials, be used with negative ions, although the detector described is not suitable in this event.

Abstract: 1415311 Electrostatic and magnetic separation TRANS-SONICS INC 25 Aug 1972 [25 Aug 1971] 39836/72 Heading B2J [Also in Divisions G1 and G2] Hyperfine particles in a fluid flow are monitored by utilising an electric or magnetic force field to deposit the particles on a substrate and then optionally monitoring selected characteristics of the deposited particles. As shown, Fig. 1, a magnet 14 having pole pieces 16, 18 defining a narrow gap produces a magneic field extending perpendicularly to a substrate 20 mounted on a tapered support 28. The substrate is provided with non-stick edging members 22 to define a flow channel down which is passed a sample of oil from an engine. Iron particles in the sample are precipitated by the magnetic field, the large particles first, followed by the smaller particles, thus producing a graded distribution according to particle size. Preferably the sample is mixed with a "developer" e.g. perchlorethylene, to break the oil-particle bonds. After deposition of the particles the substrate is flushed with developer to remove residual oil and then with a "fixer" (e.g. trichlorethylene) to remove the developer. The resulting slide may be viewed by a microscope, e.g. using the two colour illumination technique of the divisional Specification 1415312-see Division G2-or by a photoelectric densitometer which measures the transmissivity of the sample at a plurality of selected points along the distribution the results being presented as the individual concentrations, the first er second time derivatives of these concentrations or the ratio of the concentrations at two points. In an on-line system, Fig. 13, a minor bypass. in an oil line includes a transparent tube 92 subjected to a magnetic field by a magnet 98. A lamp 94 illuminates the particles deposited on the wall of the tube and measurements are made by a densiometer 100 which may utilise a plurality of photocells to monitor different parts of the particle distribution. It is preferable to utilise an electromagnet which is switched off between measurements to allow the particles to be washed away by the oil flow. An electrostatic embodiment is described with reference to Fig. 14 (not shown).
